There's nothing you can do except offer your condolences. After all, she lives in another country and you said you are not very close. If she has a close family, I am sure they are all she needs at this time.

Just remember her child. That's all we want, those of us who have lost a child. We want acknowledgement that our child is a part of our family and always will be. We want acknowledgement that this Childs life and loss is such a huge, hideous loss and will change us forever. We will always love our child in the present tense.

Send a card/letter. Mention the Childs name. Ring her every so often. Grief is isolating and endless. Perhaps a friend who is one step removed is just the type of person she can let go to. We protect those we are close to from the horrors of grief.

Be kind and gentle with her. Forgive her her silences or rages. She is forever changed.
